Have ran them on our Co Motion tandem in 700x28 & my Co Motion touring bike there not to bad of a tire for the price and there durable & wear well ( I like them). A lot less in cost than the Ultra Gator skins mentioned (have ran Gator Skins on the tandem & touring bike to, good tires as well) they do weigh a little more than the Gator Skins mentioned not a big deal in my opinion..

Ride Safe All,
